Patch from Kirk McKusick to fix an ordering problem in softdep_setup_freeblks()

Get rid of some old unnecessary code that cleared B_NEEDCOMMIT from buffers in

in ufs_balloc_range(), don't rely on uvm_vnp_setsize() to invalidate

pages we've allocated past the real EOF when we fail to allocate a block.
we used to play games with the VM notion of the file size but we don't do
that anymore, so uvm_vnp_setsize() doesn't do what we want anymore.
call the pager flush op instead.

Correct accounting of lfs_avail, locked_queue_count, and locked_queue_bytes.
...
(PR #11468 ). In the case of fragment allocation, check to see if enough
space is available before extending a fragment already scheduled for writing.
The locked_queue_* variables indicate the number of buffer headers and bytes,
respectively, that are unavailable to getnewbuf() because they are locked up
waiting for LFS to flush them; make sure that that is actually what we're
counting, i.e., never count malloced buffers, and always use b_bufsize instead
of b_bcount.
If DEBUG is defined, the periodic calls to lfs_countlocked will now complain
if either counter is incorrect. (In the future lfs_countlocked will not need
to be called at all if DEBUG is not defined.)

In lfs_truncate, don't overcount the real blocks removed from the inode,
...
when deallocating a fragment that has not made it to disk yet.
Also, during dirops, give the directory vnode an extra reference in
SET_DIROP, to ensure its continued existence during SET_ENDOP, preventing
a possible NULL-dereference there.
These two changes should close PR #11064 .
